I have a 2011 13inch Macbook pro. When playing video on amazon prime or netfilx I have a stuck bright blue tiny pixel in the top left side of the screen. It disappears and works perfectly when I leave the video and also doesn't seem to appear when watching youtube or BBC iplayer. How can I fix this and why is it doing it?
The issue doesn’t appear when doing the same on Chrome or Firefox. I’m completely stumped as to what it is. Help!?!
